The sound of pacing woke Spike up. He sat up from his basket and grumbled. He grabbed his clock and headed towards the source of the pacing. When he opened the door to the library’s foyer, he was greeted by the sight of his guardian pacing in circles. A worried expression was on her face.
“Twilight,” he said. “I put up with a lot of things from you. You constantly asking me to clean up your messes, you making me re-shelf the shelves when there’s a single book missing, you asking me to keep your secrets safe when you dictate your diary to me, and I ask for only one thing in return: time to sleep. For what I believe to be the fourth night in a row, you have broken that agreement. Am I going to have to show your innermost secrets to everypony?”
“It’s not that late,” she replied. “And this is really worrying me.” Spike threw his alarm clock to her. A purple glow caught it and brought it to Twilight’s face.
“4:22 AM,” Spike grumbled, “Not that late huh?” A guilty look appeared on her face.
“I’m sorry Spike,” she said. “But this feeling I feel, I don’t know what it is. It’s just so confusing!”
“I know, I wrote those words in your diary,” a sigh escaped the sleepy dragon’s mouth. “Look, obviously you can’t deal with this on your own. Why don’t you talk to somepony about it? Preferably somepony who knows how the heart works, namely Rarity.” Twilight stopped her pacing.
“That’s actually a good idea,” Spike made his way back to bed. “I’m surprised that you’re not asking to come with me.” He stopped at the door and a small frown appeared on his face.
“I promised Pinkie I’d help her with a little…let’s call it a personal project,” he answered. He entered the room and returned to his basket. Besides, what’s the point if seeing her only hurts me?
Pinkie looked to her wall in concentration. On it, were pictures of every citizen in Ponyville. Coloured strings were attached to each picture. Her eyes were focused on a picture of a purple unicorn mare. A yellow string was attached to it and leading to her own portrait. The string was coloured black at Pinkie’s picture. How am I going to do this? A knock brought Pinkie back to reality.
“Come in,” she said. The door opened and Spike entered her room. “Hi Spike. I’m glad you came to help me with this.” He walked towards the pink pony.
“Glad to help,” he said. “Though I am curious as to what ‘this’ is.” Pinkie pointed to her wall. Spike turned to it. His eyes widened at the sight.
“Ah, that’s what,” he looked to Rarity’s picture. Attached to it was a red string leading to a picture of Applejack. A sigh left his mouth. Pinkie put a hoof on his shoulder.
“I’m sorry, Spike,” she said. “I just want you to know, I had no part in that. It developed on its own.” He pushed her hoof away.
“I know, but that doesn’t stop me from hurting,” Spike tapped the floor. “So, what is it you needed my help with?” Pinkie pointed to both her’s and Twilight’s pictures.
“That,” she said. “Twilight has feelings for me, but I don’t feel the same. Since you’ve lived with her all your life, you know her the best. How can I let her down without breaking her heart?” Spike sat down. He crossed his legs and arms, closing his eyes. Pinkie sat herself down and stared at the dragon. He slowly opened her eyes.
“Here’s what I think,” he began. “Twilight is an intellectual pony. She’s run by logic and isn’t swayed by emotions that often. She’s worried about these weird feelings she has whenever she thinks of you, and she’s not thinking logically. All you have to do is point out why you two as an item would not work logically.” Pinkie tapped her chin.
“That could work,” she said. “If I actually ran by most ponies’ logic. I can’t think like a logical pony! One of my key philosophies is ‘eat sugar, do random things’! I don’t think I can do that!” Spike chuckled.
“And that’s where I come in. Like you said, I’ve lived with Twilight my whole life. I’ve absorbed some things from her. I think I should be able to write you…” he stopped as his cheeks puffed out. Pinkie moved out of the way as a jet of green fire escaped his mouth. A scroll materialized from ashes on the floor.
“Huh, so that’s how it works. What’s it say?” Pinkie asked. Spike unrolled the scroll and began reading. His jaw dropped as he reached the middle section.
“No way,” he said. Pinkie tilted her head in confusion. Spike rolled the scroll back together. “Apparently, you and Twilight are sisters.” A large gasp escaped Pinkie’s mouth.
“So that’s why Twilight’s mother kept visiting the rock farm when I was little!”
“When I was still at the farm, this white unicorn with a purple and white mane kept visiting. My sisters and I called her our Aunt Velvet. She wasn’t really our aunt though, my mom, well I guess she’s my adoptive mom now, and dad explained that she was a friend of the family.”
“How does that make you two sisters?” Pinkie hopped around the room.
“Think about it,” she answered happily. “Why would a random mare constantly visit a far off farm to check up on the family?”
“To see if the children were growing and safe?”
“Exactly! This is so great! I can throw a big party for Twilight and myself! And I’ll invite everypony from my father and sisters, to my mom and her son!” Pinkie stopped mid-hop and fell to the ground. “Oh no.”
———————[Time Limit Reached]———————
“What’s wrong?” Pinkie looked directly at Spike, in her eyes was pure terror.
“You said that Twilight had these weird feelings whenever she thought of me right?” Spike nodded. “What did you tell her to do with that feeling?”
“I told her to go to Rarity,” he answered. “She knows how the heart works. And she should be able to… oh no.” Spike’s eyes widened.
“Twilight has gone to Rarity’s,” Pinkie began.
“To talk to her about these weird feelings that she has been feeling for another pony,” Spike added.
“And Rarity is going to interpret that feeling…”
“AS ROMANTIC LOVE!” they both screamed. Spike hopped on Pinkie’s back.
“We need to stop her and tell Twilight the truth!” Pinkie ran towards an open window.
“Way ahead of you little buddy!” She jumped from her window towards the ground. When she landed, she galloped as fast as her legs could carry her towards Carousel Boutique.
Two unicorns sat in Carousel Boutique. Between them were two cups of tea and a kettle. A smile was on the proprietor’s face.
“Well it’s obvious as to what you should do, Twilight,” Rarity said. “You should go to Pinkie, and tell…” she was interrupted by a nearby window shattering. Both unicorns turned their heads to find a pink pony jumping through the window frame. On her back was a purple baby dragon with a scroll in his hands.
“Pinkie!” Rarity shouted. Said pony was shaking glass of herself. “Why have you decided to break my window?! Those are expensive to fix!”
“I’m sorry Rarity, but I needed a quick way in,” she turned to Twilight. “Twilight, I have something very important to tell you.” Twilight’s heart quickened. A faint blush appeared on her face. She shuffled her hooves together.
“Actually, I do too,” Twilight swallowed her nervousness. “You see Pinkie, I love…” she stopped mid-sentence. Twilight took in a deep breath. Before she could continue, she was hugged by Pinkie.
“I love you too, Twilight,” she said. Twilight’s eyes widened. She approached Pinkie for a kiss. Instead of her lips, she was greeted by Pinkie’s hoof. “Not that way, unfortunately. I love you like a sister.” Twilight’s expression dropped.
“She actually has a reason too,” Spike said. He handed the scroll to Twilight. “You two are actually biological sisters.”
“What?!” Twilight read the scroll’s contents.
“See, what you were feeling wasn’t eros, it was agape! Or maybe it’s storge. I know you feel philia since we’re friends, but that’s beside the point,” Pinkie again hugged Twilight. “I do love you, I really do. But it’s the same love I have for my family.” Twilight returned the hug.
“I love you too, little sister.”
This was a kinda interesting way to take the prompt. I’m kind of curious as to how a pair of unicorns could produce an earth pony, but then again there’s always Pound and Pumpkin Cake and trying to decipher how pony phenotypes work makes my head hurt anyway. What I’m more curious about, actually, is why Pinkie was given to the Pies instead of raised with Twilight and Shining in Canterlot. If you ever decide to go back to this story and expand on it, I think that’d be a good place to go into. Overall, though, a good story. Great job, Shingo!
